Knowledge and Perceptions of Influenza Vaccinations Among College Students in Vietnam and the United States.

ABSTRACT: Influenza is a significant worldwide public health issue. Knowledge and perceptions regarding the flu vaccination are associated with whether individuals obtain the vaccination. The purpose of this study was to examine how such perceptions were related to knowledge and self-efficacy regarding influenza and the flu vaccination in Vietnam and the US.College students (n=932) in Vietnam (n=495) and the US (n=437) completed a self-administered survey regarding knowledge and perceptions of influenza vaccinations in September and October 2016.Vietnamese participants reported significantly lower levels of awareness about flu risk, higher levels of negative attitudes toward flu vaccination, lower levels of knowledge about the flu and vaccination, and lower levels of self-efficacy than US participants. Higher levels of flu and flu vaccination knowledge and self-efficacy regarding general responsible health practices were associated with lower levels of negative perceptions of flu risk and attitudes toward vaccination. At the same time, self-efficacy regarding responsible health practices was associated with higher levels of awareness of flu risk and lower levels of negative attitudes toward vaccination. Self-efficacy regarding exercise was associated with lower levels of perceptions of flu risk and higher levels of negative attitudes toward vaccination.Vietnam could benefit from influenza education based on this comparison with the US. In both countries, knowledge and self-efficacy were found to be important factors influencing perceptions of influenza risk and vaccination.

Project description:BackgroundDespite evidence for the harms of waterpipe tobacco smoking (WTS), its use is increasing amongst college and university students worldwide. This systematic review aims to assess the knowledge of, attitudes towards and perceptions of WTS among college or university students.MethodsWe electronically searched MEDLINE, EMBASE, CINAHL, PSYCHINFO and ISI the Web of Science in October 2018, restricting our search to studies published since January 1990. We included studies among university or college students that used qualitative or quantitative methods, and addressed either knowledge, attitudes, or perceptions towards WTS. We excluded studies where WTS could not be distinguished from other forms of tobacco use and studies reported as abstracts where the full text could not be identified. Data were synthesised qualitatively and analysed data by region (global north/ south), and by reasons for use, knowledge of health hazards, how knowledge influences use, perceptions towards dependence, and policy knowledge.ResultsEighty-six studies were included; 45 from the global north and 41 from the global south. Socio-cultural and peer influences were major contributing factors that encouraged students to initiate WTS. Furthermore, WTS dependence had two components: psychological and social. This was compounded by the general perception that WTS is a less harmful, less addictive and more sociable alternative to cigarette smoking. Knowledge of WTS harms failed to correlate with a reduced risk of WTS use, and some students reported symptoms of WTS addiction. A large proportion of students believed that quitting WTS was easy, yet few were able to do so successfully. Finally, students believed current public health campaigns to educate on WTS harms were inadequate and, particularly in the global north, were not required.ConclusionReasons for WTS amongst university students are multi-faceted. Overall, interventions at both the individual and community level, but also policy measures to portray a message of increased harm amongst students, are required. Additional studies are necessitated to understand temporal changes in students' beliefs, thus allowing for better targeted interventions.

Project description:BackgroundPrescription drug misuse is an escalating public health problem that is prevalent among college students. Various factors, such as sex, age, race, mental health conditions, and fraternity and sorority membership, increase the risk for prescription drug misuse. Peer influences may also pose significant risks for starting prescription drug misuse, because peers are the primary source of misused prescription drugs among college students.ObjectivesTo examine college students' beliefs about prescription drug misuse among their peers and to understand their beliefs about the available and potential intervention efforts to reduce prescription drug misuse.MethodWe conducted a cross-sectional survey of 312 college students aged 18 to 30 years who were enrolled in a large midwestern US university. The survey included questions about the responders' demographic characteristics, beliefs, and perceptions regarding prescription drug misuse among their peers and potential reduction programs for prescription drug misuse.ResultsThe respondents' mean age was 21 years, and most (65%) respondents were women. A majority (90%) of the respondents were enrolled in the university as full-time students. More than 60% of the respondents reported knowing someone with prescription drug misuse in the past 12 months. Fraternity or sorority members were more likely to report peer prescription drug misuse than nonmembers (83% vs 60%, respectively; P = .017). Stimulants were the most misused drug class, accounting for 75% of all reported peer prescription drug misuse. Approximately 60% of the misused prescription drugs were sourced from peers, which included friends, roommates, and classmates. A total of 73% of respondents said that prescription drug misuse was a problem among college students and 67% agreed that interventions were needed to reduce prescription drug misuse. The perceived need for interventions varied by peer prescription drug misuse. A total of 90% of students whose peers did not misuse prescription drugs said that interventions were needed, but only 67% of those with peer prescription drug misuse thought that interventions were needed.ConclusionOur findings indicate that peer prescription drug misuse is very common among college students, and the most misused drug class is stimulants. Survey respondents perceived that the current interventions used to address prescription drug misuse are not very effective or may not be targeting the right population. Peer prescription drug misuse influences college students' perceptions about the risks and harms of prescription drug misuse, as well as the need for interventions.

Project description:ObjectiveThe study objective is to analyze influenza vaccination status by demographic factors, perceived vaccine efficacy, social influence, herd immunity, vaccine cost, health insurance status, and barriers to influenza vaccination among adults 18 years and older in the United States.BackgroundInfluenza vaccination coverage among adults 18 years and older was 41% during 2010-2011 and has increased and plateaued at 43% during 2016-2017. This is below the target of 70% influenza vaccination coverage among adults, which is an objective of the Healthy People 2020 initiative.MethodsWe conducted a survey of a nationally representative sample of adults 18 years and older in the United States on factors affecting influenza vaccination. We conducted bivariate analysis using Rao-Scott chi-square test and multivariate analysis using weighted multinomial logistic regression of this survey data to determine the effect of demographics, perceived vaccine efficacy, social influence, herd immunity, vaccine cost, health insurance, and barriers associated with influenza vaccination uptake among adults in the United States.ResultsInfluenza vaccination rates are relatively high among adults in older age groups (73.3% among 75 + year old), adults with education levels of bachelor's degree or higher (45.1%), non-Hispanic Whites (41.8%), adults with higher incomes (52.8% among adults with income of over $150,000), partnered adults (43.2%), non-working adults (46.2%), and adults with internet access (39.9%). Influenza vaccine is taken every year by 76% of adults who perceive that the vaccine is very effective, 64.2% of adults who are socially influenced by others, and 41.8% of adults with health insurance, while 72.3% of adults without health insurance never get vaccinated. Facilitators for adults getting vaccinated every year in comparison to only some years include older age, perception of high vaccine effectiveness, higher income and no out-of-pocket payments. Barriers for adults never getting vaccinated in comparison to only some years include lack of health insurance, disliking of shots, perception of low vaccine effectiveness, low perception of risk for influenza infection, and perception of risky side effects.ConclusionInfluenza vaccination rates among adults in the United States can be improved towards the Healthy People 2020 target of 70% by increasing awareness of the safety, efficacy and need for influenza vaccination, leveraging the practices and principles of commercial and social marketing to improve vaccine trust, confidence and acceptance, and lowering out-of-pocket expenses and covering influenza vaccination costs through health insurance.
